20% (35 chars) of screen space permanently wasted on a always on file browser (meanwhile the animation showcases fuzzy finding)
4% (7 chars) of screen space permanently wasted by line numbers (why are the numbers cut off on the right?)
2.7% (5 chars) of screen space taken up by a gutter
So 27% of screen space effectively dead 99% of the time.
Why do people do this to themselves?
I can't quite figure out how to get the gutter to truly only appear when needed (I can't remember why) but in my vim configuration 2 chars of space are taken up by the gutter and the rest is for the actual code. The current line number is in the bottom right, and if I need to go to a specific line number I have `G` for that. If I need a file explorer, there's the default Netrw one, there's NERD Tree, there's a terminal (I actually rarely need this anyway, but I can understand not everyone can cope, but I can't comprehend why you would need it on 100% of the time).
Why does the "modern text editor" waste so much screen space?
I have a 1200p laptop monitor which gives me 174 chars of horizontal space at a comfortable font size. If I split that in half I get two terminal windows worth of 87 characters each. If I keep my code under 85 characters per line, not only is it easier to read, I can keep a man page or another piece of code on the other half of my screen.
